Athrotaxis cupressoides is an endemic conifer restricted to montane areas of Tasmania. It slow‐growing and vulnerable the increasing wildfire activity associated with climate change. We explored novel idea that disused gravel pits could serve as artificial fire refugia for transplanted populations. compared survival, growth, response fertilizer nursery‐grown A. transplants in these refugia, which had mineral soils, burnt unburnt sites wilderness areas, organic soils. Survival over 16‐month trial increased initial transplant height was slightly higher (97%) than (89%). Height growth unfertilized plants slow, especially pits. However, boosted most strongly pits, rates similar those fertilized sites. Our results show it feasible reintroduce into populations eliminated by wildfire. They also demonstrate capacity reclaim creating new localized this iconic species. Thus, denuded can be re‐imagined help maintain other long‐lived but fire‐sensitive wild.

An unresolved, key question in plant ecology and biogeography is the relative importance of fire disturbance edaphic factors controlling treeless-forest boundaries. We investigated similarities differences soil physical chemical characteristics Sedgeland, Scrub Eucalyptus Forest sites around a large treeless area (Blakes Opening) situated densely forested Huon Valley southern Tasmania. In each community, risk was also assessed over 12 months using microclimate measures above-ground temperature humidity, water tables were monitored seasonally. Sedgeland soils upper layer organic (18–38 % C) sand rich (c. 75 mineral fraction), differed fundamentally from inorganic 5 C 55 sand). had much lower bulk density significantly concentration capital most nutrients (except C, N S) rootzone. Ordinations both rocks profiles discriminated Forest, with being intermediate. winter, higher than Scrub. However, has drier microclimate, which makes its fine fuels available to burn more frequently for longer period summer compared Forest. This confirmed by radiocarbon dating charcoal, showed that regular feature this environment throughout Holocene. The strong differentiation Sedgeland-Forest boundaries at Blakes Opening calls into prominent theory vegetation patterns region are shaped primarily landscape fires.
